I started a session just before going to bed. This never works out for me. I drift off to sleep before anything gets started.
It worked out this time, though. Fuck me running, did it work out.
I felt a slow pulsing at my anus that maintained a persistent stimulation, and a much slower internal stroking that triggered a wave every forty seconds, I estimate, that amplified the stimulation. The two different internal contractions kept their slow, relentless paces, escalating my arousal to levels I hadn't thought possible.
I now understand what “do nothing” means. In previous sessions, there were points where sensations would start evaporating, and I'd contract something or pluck something else to get things rolling again. This time was very different. Nothing needed doing. The only moments of exertion were when the stimulation got a little unstable, and I fought my body's reflexive need to fold in half at the abdomen.
One of those instabilities got too strong for me. I released a low, sad whimper. My body spontaneously crumpled up like a paper ball, and did not unwad itself for many seconds.
After acknowledging that one of the most intense sexual experiences of my life had really happened, I started dreaming without being entirely asleep. This was a familiar sign that the session was over, and I should clean up and get some sleep. I still had a residual tingle, and thought it would be like a delightful warm breeze to waft me into unconsciousness.
